Is it the lock button on top of the door or the latch that holds the door shut? If its the latch just pull door handle then flick catch back round with a screwdriver. Its a C lock that spins round when door shuts locking the door in place, when handle is pulled, the C lock is released and spins back with the effort of the door opening. Hope this helps
With your key in the door lock cylinder.
The fuel door should open as long as the doors are unlocked. It locks once the doors are locked.
Open the handle while pushing the inner workings of the latch open.
When you open the door, there is a sliding switch in the facing of the door itself, usually near the latch. There's usually a sticker near it telling which way is locked. When the child locks are activated, the door cannot be opened from the inside.
To disable the child locks on an Alfa Romeo 159, open the rear doors and locate the child lock mechanism on the edge of each door. Use a flathead screwdriver or a key to turn the mechanism from the locked position (usually marked with a lock symbol) to the unlocked position (marked with an open symbol). Ensure you repeat this for both rear doors, and then test the doors to confirm that the child locks are disabled.
It could be a little switch in the door that just needs to be flipped
You can open a locked door (From the outside: With a key)(From the inside: With the lock opener, usually by twisting it) :-)
To engage the child locks on a 2001 Ford Focus, open the rear doors and locate the small lock mechanism on the edge of the door. Use a flathead screwdriver or your finger to slide the lock to the "lock" position, which is typically marked with a small icon indicating a locked door. Repeat this process on the other rear door. Once activated, the child locks will prevent the rear doors from being opened from the inside.
Get very thin eyebrow twizers, and pull the broken lock! Listo..
You can not close any door if the locking mechanism is stuck in the locked position. You must first get the mechanics to unlock.
If the door won't open from the inside, then maybe it's due to the child safety locks. If it won't open from the outside, then maybe it's locked, or the door handle mechanism has broken, as it has on my 1998 Civic. From the inside, you might be able to remove the screw holding the handle and slide the handle set forward to remove it from the door.
It is not recommended to use a credit card to open a locked door as it can damage the card and the door. It is best to contact a professional locksmith for assistance in opening a locked door.
